<p>Freediver Jules Casey captured footage of thousands of spider crabs, which could be seen stacking in layers across the ocean floor off Port Phillip, Victoria.</p><p>She said the layers were three or four crabs deep. When a commenter asked if fishermen could capitalise on the crabs, Casey said “there’s no meat on these crabs and they taste like mud apparently, so not good for eating”.
